grub不显示Windows 8安装

Question

我在我的MacBook Pro上有一个Ubuntu14.10/MacOSX/Windows 8三引导。

但是，Windows没有出现在grub中，只有MacOS和Ubuntu出现。

我从其他类似的问题中尝试了一些东西，但是没有什么效果，比如运行update-grub或Boot Repair。以下是一些可能有用的程序输出：

fdisk

sudo fdisk -l

我想/dev/sda3 3可能是windows !？

更新-grub

尝试更新存储库，希望这将有助于您在windows 8中使用GRUB。

sudo add-apt-repository ppa:yannubuntu/boot-repair &&

sudo apt-get update &&

sudo apt-get install -y boot-repair &&

boot-repair
